' Referring now to the accompanying drawings in which like letters andnumerals nism, this of reference indicate like parts in all the figures,1 designates the main frame whichhas bearings 33 to support the centralshaft 2 which carries the turn-table or wheel 4, whose hub, 4: is keyedor otherwise rigidly secured to the shaft 2. The wheel 4 carries 7 thefemale mold or die carriers 5, which are -formed in half sections andare hinged to-' gether by pins 'Gsecm'ed to the wheel 4. Each moldsection has its pivot end 5' cut 'to form. shoulders or sockets 5 whichprevent the mold sections 5 from meeting. Each female mold section alsoincludes the arms 5 which are cut away-to leave a slot 7 and permit aslight amount of resiliency to reside in such arms 5, for a purposewhich will hereinafter be more clearly uns derstoed'. At the ends of thearms 5 are the female molds proper, each of which is of like form andhas as many compartments or die sections as may be desired, four beingshown in the drawings.

A ring 10 is suspended beneath the wheel proper 4-, by brackets 1O thatdepend from the spokes 4t. (in the rim 10 a set of links are pivoted at8*, one for each set of molds and the links 8 project up through theirrespective slots 7 and operate therein.

12 designates forks whose lower ends are reduced and tapped at 11 intothe peripheral rim dof the wheel l and form a center guide for thefemale mold sections as well as a support to which the inner latches 9are fulcrumed at 9*. The forks 12 support the-latches 13 for the maledie sections and serve as guides for the bars 14 thereof. The

bars 1d are hinged at 14c to the respective links 8 and have heads 14that carry the male dies or cores 15 and the oven caps or hoods 18, aswill hereinafter more fully appear. Each latch 13 is pivoted at 13- nearthe upper end of the respective fork l2 and is composed of two sections,the lever section 13* and the finger 13 which is pivoted thereto at T3and tends continuously to move in one direction under the influence of aspring 13 The lever portion 18 of each latch 13 at its free end carriesa roller 13 to engage the track 46 that serves to release the latches 13during a proper interval of the operation of the machine and to engagethe track 46 that restores the latthes 18 to their latching position.

Each female mold section has one or more suitable half dies 5, whoseinner surface is roughened to retain the cone after it is baked andmolded and while being released from the male die or core 15. Each diesection 5 has a double grooved mouth 5 -57, the latter groove 57receiving the collar 58 of the corresponding core 15 to effect a closureof the female die. Each die section 5 also carries one-half of an oven16*, whose hood 16 is carried on the male die carrier it, beforereferred to. The side walls of the oven l6 are spaced from the dies toafford passages 16 for the heat, as best shown in Fig. 13 of thedrawings. The cores 15 are swivelly connected to the head 14 at 15 by aball-like joint. The latches 9.have notches 9 (Fig. 10) to rest over thearms 5 of the mold sections and hold them together after they have beendrawn together in a manner hereinafter referred to. Springs 53 connectto one of the female die sections of each set and to the wheel rim 4: tocontinuously tend to hold those sections against the stop pins 52,provided on the wheel rim 4: to arrest the movement of the female diesections. Those of the die sections having no springs 53 are moved by aspecial mechanism, hereinafter described. The latches 9 have pendentmembers 9 that project downwardly through is past, whereupon the guidethe slots 7 and are engaged by a traclr 51. at the proper time torelease the latch heads from engagement with the die arms to re leasethe same while the molds are being emptied. The track 51 is suitablysupported on standards 51* secured to a beam 5 beneath the wheel 4%.Each male die head has at its free end. a notch 14 on its under side andit also carries a roller 1 to ride on the traclr l7 that is provided forslightly lifting the cores from the female dies to cause them to disengage the cones before the cones are released from the dies and droppedto the trimming mechanism. The track llis sup ported on standards 47that are carried on the bracket 4.? and assists in maintaining the beam51 in place. After the latches 9 are released, the molds are opened bythe spring 53 and by a mechanism best shown in Figs. 2 and 5, byreference to which it will be seen that on front of each of the moldsections to which the springs 53 are connected, is a lever 18 that ispivoted at 18*, the lever 18 having rolls 48 and 5d at each of its ends.The levers 18 connect to the opposite molds by links 18 that are pivotedat one end to the upper end of the levers 18 at 18 and are pivoted at 18to their respective mold sections; Stops 18 are provided on the levers18 to limit the movement of the levers and the links when moved towardtilt their normal or latching position. The female molds are opened whenthe rolls 48 engage the guides 49 and 50 on the bracket L 4-7 and areclosed when the molds engage the guide 55 on the support 4!? as will behereinafter more fully understood.

There are four positions where the male and female molds are undergoingmovement relatively to one another and these positions are designated A,B, C and D in Figs. 2 and 5 of the drawings. At all the other positionsthe molds or die parts are locked together and move as one. The track4:? extends from position A to position 6 and performsits functionbetween these positions. The (ipening guides 49 and 50 come intooperation after the respective molds have left position A, and continueto perform their function until the molds leave position C. The closingdie 55 comes into operation a-t'positio-n C and remains in operationuntil Illtil the dies leave posit-ion D. The latches 9 play just beforeposition A is reached and terminates its function just after position D46 comes into play to set the latches 13. At posltion C the unloading ofthe moldsand discharge .of

the baked product takes place and at poconveys them to the trimmingmechanism, .also to; be hereinafter explained.

Burners 17 are located beneath the molds at each position of theirtravel except positions B, O and D, and are arranged alternately, thatis to say they are arranged so that their heat is applied first to oneside of the dies and ,then to the other side, as the wheel carries themaround the circle.

Mechanism for supplying dough to the molds is best illustrated in Figs.2, 3, 4 and /9 of the drawings, by reference to which it 1 ill beobserved that upon a suitable sup- 20 port 23 is located the doughreservoir 19 that has an outletl9 governed by a valve 27 whose stem 27extends downwardly through the ofl -take pipe 26-to the bottom thereof.A. suitable frame 22 is pivoted at 22 on the bracket 23 secured to thesupport 23 and carries an adjust-able counterweight 24 tocounter-balance the weight of the dipping tank 25 that is removably heldin the pocket 22 of the frame 22. Movement of the frame 22 under theinfluence of the weight 24 is arrested bya stop 59 and is normallyadjusted so that the pocket 22 will rest lightly on the table 23 Thedipping tank 25 has a spout 25 having an up-turned end 25 into which thepipe 26 projects and has a sliding movement therein. Mounted in bearings20 is a rock shaft 20 having an arm 20 -provided with a finger 2O toengage the notches 14 in the heads of the male die carrier arms. Theshaft 20 has a fixed clutch member 21 and a loose clutch member 21,which member 21 is shiftable by suitable lever'devices 21 and is alsoprovided with a counterweight 21, as indicated. The member 21 also has apulley portion 21 over which the cable 41 iswound. The cable 41 passesover an idler 41* (see Fig. 9) and has its ends secured to a rockerframe 39 which is pivoted at 39 to a support and carries a roller 40that is held in the cam' groove 37 of a gear 37 on the main shaft 36.The main shaft 36 is driven from the driving shaft 38 by a pinion 38 andthe driving shaft 38 gets power by a pulley 38 and belt 38, orotherwise, from any source not shown. The shaft 36 in turning causes therocker frame 39 to oscillate at proper intervals, thereby causing theshaft 20 to rock. The movement of the shaft 20 brings the finger 2Obeneath the head 14 of the male mold section into alinement. therewithat position B, and entering the notch 14? thereof raises the cores outof the molds (see Fig. 3) and moves them upwardly and out- 5 wardly overthe tank 25 and then downwardly to dip the cores 15 into the dough inthe tank 25, as shown in; full lines in Fig. 3, after which the movementof the shaft 20 is reversed and the molds or cores 15 are lifted fromthe tank 25 with the dough adhering thereto, and returned to the femalemold. In order to counterbalance the Weight of the links 8 and the. partcarried thereby in dipping the cores, a leaf sprin 56 is held to beengaged bythe respective links when they move from the position shown indotted lines in Fig. 3 to the position shown in full lines in the samefigure. Thus the spring 56 holds the notch 14 always over the finger 20and prevents slipping of the parts.

The mechanism for imparting a step-bystep movementto the wheel 4, isbest shown in Figs. 8 and 9 of the drawings. It will be seen that theunder face of the rim 4 has carries the latch bar 43. The bar 43 is pivoted at 43 to the arm 42 at its upper end.

The latch bar 43 has a notch 43 in its front end and has a heel 43 atits rear end with which the,crank42 engages to lower the clutch end 43from engaging the wheel blocks 4 on the return stroke of the pitman 42".The foregoing constitutes the step-by-- step feeding mechanism whichwill, as the shaft 36 turns, cause the army 42 to be rocked and the chich bar to alternately engage and disengage the wheel and move it forwardstep-by-step on the forward stroke of the pitman 42 to turn the Wheel inacounter-clockwise direction in Figs. 1' and 2.;

In order to' renderthe feeding mechanism inoperative when desired, itonly requires that the bar 43 be prevented from interlocking with theWheel 4 and this is done by a lever 44 pivoted at 44 and movable underthe heel 43 by a rod 44* to preventthe crank 42 from engaging the heel43.

Wheri the cones are'discharged from the molds at positionC they descendinto the trimming mechanism where the rough-edgesof the mouths are takenoff and this mechanism is best disclosed in Figs. 5,6 and 7 of thedrawings, from which it will be noted, suitable tubes 28are supported ona platform 29 and have their upperedges sharpened to trimthe edges ofthe cones as they pass through the tubes. As the cones are chuted intothe tubes 28 they will hang until trimmed. In order that the trimmingoperationmay be completed, a plate 30 is pivoted at 30 to a supportandheld up by a spring 30*. The plate 30 has a soft rubber cushion 31 whichengages the cones in the tubes 28 and pushes them through. When theplate 30 is moved to cause the cushion 31 to engage the cone, as shownin dotted lines in Fig. 5," it thereby causes the sharpened edges of thetubes 28 tosever the projected parts of the cones, which parts thereuponfall into the pan 29 and may be chuted at 29 to any desired place. Themovement of the plate 30 is etfected at intervals by a suitablemechanism, such as indicated in the drawings. ltods 32 and cams 32 on.the shaft 35 serve to operate the plate 30, the shaft 35 being drivenfrom the main shaft 36 by gearing 35*, as shown in 7.

r A conveyor 35* driven from the shaft 35 receives the cones from thechute 34: and carries them to the outside of the machine, where they maybe delivered into any suitable receptacle (not shown).

Having thus described the construction of my invention and indicated theoperation in a more'or less general way, a moredetailed description ofthe operation of the machine is now in order,

Assume power to be applied to the belt 38 to set the shaft 36 in motionthereby causing a step-by-step movement to be imparted to the wheel 4t,as before described. Assume also that dough is in the reservoir 19", thetank 25 being full, valve 2? closed, burners 17 being lighted, and wheel4 at one of its rest positions. Assume also that the mold at position Dhas just arrived at that place and the female mold sections thereof arelocked together. As the shaft 36 turns and the shaft 20 is rocked asheretofore described, the finger 20* is now brought into engage mentwith the notch 14 of the head 14: at position D, when the parts are nowpositioned as shown in dotted lines in Fig. 3. The arm 20 now raises themale mold or core out of the female mold (see dot and dash lines Fig. 3)and moves through the are indicated in such figure, moving the arm 14 inthe direction of its arrow in Fig. 3 to thereby cause the pivot 1 1' torise as the link 8 moves over toward the position shown in 1 fu-ll'linesin Fig. 3. Then the cores 15 are.

carried over the tank they are lowered therein and a quantity of doughadheres to each of them, whereupon" the movement of the shaftis reversedand the cores 15 are returned to the female dies, as shown in dot-tedlines in Fig. 3, closing the molds and squeez ing the dough into placetherein. The dipping of the cores 15 into tank and the con sequentialremoval of the dough therefrom causes the weight 2t to raise the tank25, thereby opening the valve 27 and allowing dough to flow into thetank 25 until its level therein is restored, whereupon the valve 27closes off the flow of dough. The core 15 has thus been dipped andreturned to the molds 5. The wheel 4 is now moved forward step-by-stepover the burner 17 to bake the dough as the molds move from position Dover the burners, the latch 13- will dis engage the track t6 and bestraightened out,

nevi-par to lock the male section of the molds in place, by the guides40. The molds are-now moved step-by-step around the circle from positionD to position A, during which time the baking operation is taking place.W hen the mold reaches the position just in advance of position A thelatch roller 13 engages the track 4:6 and releases the latch 13 from themale section of the die. When the mold reaches the position it, theroller Lt on the end of the carrier will ride up on the track l? toslightly raise the cores 15 out of the mold 5, the swivel ballconnection between cores 15 and the head 14" being such that thismovement may take place without disturbing the centering of the cores 15in the cone. This raising of the cores releases them from the bakedcone. During the next step of movement of the wheel the mold at positionA moves to position B, and in so doing the latch 9 is released and thelever 18 engages the guides 49 and 50 to begin to open the mold 5 forthe purpose of releasing the baked cone. lln passing from position B toposition C the mold is fully opened and the cones drop onto the chute 30from whence they pass to the trimming mechanism and are trimmed asbefore described. The next step brings the mold from position C toposition T), during which movement the sect-ions of the female mold areagain locked together as before described and the foregoing cycle ofoperation is repeated. It will be observed the entire op eration of themachine from thetime the batter is placed in the reservoir 19 until thetinished product leaves the conveyor 35, is entirely automatic and doesnot require any manual help. The construction of the oven 14? and itscap 16 is suchthat the heat is retained as much as possible while stillallowing ample draft from the burners and by alternately heating firstone side of the molds 5 and then the other, an even baking action isbad.

' llfv it is desired not to dip the cones the clutch 21 is thrown out ofmesh when the dipping cranks will remain at rest and the end of the barof the male section of the mold passes over it without dipping of thecore. If it is desired to stop the Wheel 4: and its molds the latch ofthe step-by-step operating mechanism is thrown out of mesh and the wheelwill remain at rest.

The advantages of my machine are in providing an automatic machine formaking cones, wafers and other pastry,- that is operated automatically;the shaft running at a regular speed, dipping the cores, allowing eachthe same time in the batter, which being of a uniform consistency andautomatically kept at a uniform depth in the dipping tank insures eachcore being coated to the same thickness with they batter just therequired amount to make the cone, the space between the female sectionof the and the cores 7 being-closedvby a ball or, swivel joint, causingsuflicient resistance to form a full rim at the top of the cone withoutany Waste of batter, the automatic locking of these dies and corestogether, and passing them around over the gas burners. The molds beingprovided with a hood or oven to retain the heat, and each mold receivingthe same heat for the same period of time, the batter in each mold isbaked uniformly. The heat is regulated automatically trimming thesurplus dough off the rim and the top if there is any, and again closingandlocking the molds,'dipping the cores and locking them in the mold andso on, operating each and every mold in substantially the same manner asdescribed.

Further advantages of my invention lie in providing an automatic machineWhose dipping tank is arranged so that the batter is automatically keptat a given depth; a machine whose coresaare automatically dipped intothe batter a given length of time and to a given depth; coating themuniformly; a machine whose dies and cores are provided with a ball jointto insure perfect cones and preventing the waste of material; automati-1 cally locking the molds firmly together and subgecting each -and everyone of them to the same heat for the same length of time, thereby bakingthe pastry uniformly in all the molds; a machine whose molds are pro-'vided with a hood or oven covering the entire dies, and cores, retainingall the heat and heating both dies and cores uniformly; and reducing thefuel consumpt1o -n to a minimum; a means for automatically unlocking themolds, dropping the cones out] and trimming the rims and conveying themto a place to be packed.

connection with the accompanying draw ings it is thought the completeconstruction, j

operation and advantages of my invention will be readily understood bythose skilled; in the art to which the invention appertains.
